RAIL-CHAIR.-

Specification of Letters Patent. Pajtented Apr, 30, 1912.

Applieation'fil'ed April 22, 1911. Serial No. 622,767.

To all whom it may concern: I

Be it known that I, HnNRrELLior, a citizen of the United States,residing at- St. Louis, in the State of Missouri, have invented certainnew and useful improve-- ments in Rail-Chairs, of which the followmg isa specification.

This invention relates to rail chairs and has for its primary object toprovide an improved device of this character which can be simply andeconomically made, which will be durable -and etlicientin operation, andwhich can be easily introduced into position and removed therefrom.

One of the objects of the present invention is to provide an improvedintegral construction which is adapted to be inserted into positionunder a rail and by a simple adjusting movement made to positively gripthe base flange of the rail.

Another object is to provide an improved base plate design for railchairs whereby they are adapted to be seated securely upon the railroadtiesand whereby the process of manufacture is greatly facilitated.

Other and further objects willappear in the specification and bespecifically pointed out in the appended claim, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure 1 is a fragmentary perspective view showing my improved device inoperation. Fig. 2 is a topplan view of the same. Fig. 3 is a sect-ion onthe line III,III, 2'. Fig. at is a bottom plan view of the rail\ chairdetached. Fig. 5 'isa fragmentary top plan View of the deviceillustrating the relative positions of the parts for removing Referringmore particularly to the drawings; the rail chair-comprises inanintegral piece, a base plate 1 constructed in the man ner to bepresently pointed out and provided with a pair of claws or/hooks 2spaced from each'other both laterally and longitudinally of the rail 8..The base plate lot the rail chair is preferably constructed ree tangularand has its undersiirface provided with projecting ribs-t ofwedge-shapedfcrtiss' section extending around its .perimetral edges andother intermediate Wedge-shaped ribs 5 extending longitudinally andtrans versely of the base plate and intersecting engage the base flange7 of the rail, and.

when the rail is in position in the chair, the

def

lateral gripping Walls bf the claws 2 are" just the right distance apartto snugly grip the rail. At the same time, the spike openings '6 arearranged so that the spikes 8' which are driven therethrough impingeupon the lateral edges of the base flange 7 and thus serve to lock therail in position by the employmentof only one spike on either side ofthe rail in each tie. In order to m.ake it possible to introduce therail chair into position under the rail, the diago nal'ly ioppositeclaws 2 are cut away on the bias at 2-, these inclined edges beingparallel'to each other and spaced apart a distance less than'the widthof the base flange 7.

chair, as shown in Fig. 5., can be'shoved under the rail so asto causeone ofthe claws.2 to engage one edge of the base fiafi aafter which saidbase flange mav be c V leveled and the chair moved around into position,shown in Flgs. 1 and 2, in which position the base flange issecurelyclatnped by the claws 2. The spikes 8 are then driven throughthe openings'tl into the tie, said openings 6 being preferably elongatedsomewhat to provide clearance way beneath the flange of the rail topermit the spikes 8v to.

be driven so as to clamp the rail flange 7.

nat I claim is:'

A rail chair comprising a base plate pro vided with projecting ribsextending around.

the perimetral edge thereof and longitudinal and transverse central ribsextending across said'baso plate between said perimetral-ribs' to dividesaid base plate into four sections, a pair of clamping claws stampedfrom the base platein diagonally opposite sections of By means of thisconstruction, the rail said base plate, said claws heing provicled andto be shifted into clamping relation with parallel clamping Walls andhaving the with said base flange. outer edges thereef cut on aninclination to HEwyy I 101. said clamping walls at a distance from eachL J other slightly less than the width of said in the presence ofbaseflange, whereby said chair is adapted M.
